Product Summary

A non slam check valve is a kind of check valve for stopping the reverse flow of fluid through a fluid-carrying conduit and includes a fluid dampening device to dampen the closing movement of the valve upon flow reversal.
The fluid dampening device includes a member for containing a fluid that becomes compressed upon a reverse flow of fluid through a conduit that houses the check valve. As the check valve is forced by a reverse fluid flow in a reverse direction, fluid in the fluid dampening device becomes compressed and is permitted to slowly seep out of the fluid dampening device via fluid passageways that permit only the slow escape of fluid from a compressed fluid chamber.
